TRIPLE-SPRING DRAW-G EAR.

SPECIFICATION forming part of Letters Patent No. 701,661, dated June 3,1902.

Application filed November 2. 1901. Serial No. 80,843. (No model.) I

To all whom it may concern:

Be it known that I, CHARLES WRIGHT, a citizen of the United States,residing at Everson, in the county of Fayette and State of Pennsylvania,have invented new and useful Improvements in Triple-Spring Draw-Gear, ofwhich the following is a specification.

The objects ofmy invention are the provision of a draw-gear which shallhave ample i other desirable features and characteristics constitutingthe same a perfect instrumentality for performing all the requisitefunctions.

With these ends in view my invention consists in certain novelties inconstruction and combinations and arrangements of parts hereinafter setforth and claimed.

The accompanying drawings illustrate an exampleof the physicalembodiment of my invention'constructed \according to the best mode Ihave so far devised for the practical application of the principle.

Figure 1 is a view of the gear in elevation. Fig. 2 is alongitudinalsection taken between the stringers and one side of the couplery shank.Fig. 3 is a bottom plan View. Fig.

4 is a perspective of a shim. Fig. 5' is a per spective view of adraft-plate. Fig. 6 is a perspective view of a front follower-casting.Fig. 7 is a front end view of Fig. 1..

Referring to the several figures, the numeral 1 designates the. centralstringers; 2, the end sill; 3,the body-bolster; 4, the metallicdraft-plates; 5, the bolster attachments, each bent outwardly at rightangles to the plate; 6, the end-sill attachments, each bent outwardlyand at right angles to the inner face of the plate; 7, thestringer-flanges; 8, the

stay-plate flanges; 9, the free ends of the plates; 10, the stay-plates;11, theU-shaped ends of the stay-plates; 12, notches in the edges of thestay-plates each side of the coupler-shank; 13, the frontfollower-castings; 14, strengthening-ribs of the castings; 15, theenlarged ends of, the castings;16, angular seats for the ends of theshims; 17, holes for bolts; 18, flanges for rivets; 19, the rearfollower-castin gs, constructed substantially the same as the frontfollower-castings, except that bolt-holes are provided at one end only;20, the U-shaped carry-iron; 21, the bent carry-iron; 22, the sideplates, each of which normally covers an opening through which the shimsand springs can be removed and replaced; 23, the front shims; 24, the.follower-shims; 25 the narrow ends of the shims; 26, the coupler-shank;27, the spring-yoke; 28, the two followers; 29, the rearfollowercasting; 30, the front spring; 31, the two rear springs; 32, theguides for the springs; 33, the strain-rods, passed through theattachments 5 and body-bolster;34, the bolts which secure thedraft-plates to the stringers, the said bolts passing through thestringers, the stringerflanges 7, the follower-castings, and thestayplates; 35, the side-plate bolts, which pass through thefollower-castings; 36, the bolts which secure the draft-plates to theexternal sides of the stringers; 37, the end-sill bolts, which passthrough the end sill, the end of the stay-plates, the attachments 6, thefollower-castings, and the carry-irons, and 38 represents the carry-ironbolts, which secure to the sill the U-shaped carry-irons.

It will be observed that the draft-plates are each of an integral pieceof plate-steel cut to "shape and with portions thereof bent to formmeans for attaching the same to the stringers and to receive thestay-plate, which is riveted to the lower flanges, as shown. Thefollower-castings are riveted to the inner face of a plate each side ofthe openingforthe followers. The strain-rods pass throughthe attachments5, and the casting 29 is secured to the yoke 27 by a rivetor bolt.

To adj ust the coupler and spring mechanism in a vertical plane, thecarry-irons and plates 22 are removed and the shims arranged above orbelow the coupler-shank and the ends of the follower-plates, as thecircumstances may require.

The notches in the stay-plates allow the facile insertion and withdrawalof the shims adjacent the couplershank, and the seats 16 in thefollowencastings hold the shims securely in place.

From the foregoing description it becomes apparent that I have produceda draw-gear which fulfils all the conditions set forth as the objects ofmy invention. The construction is simple, comparatively cheap in firstcost, amply strong, and the spring capacity can be adapted for theparticular service.

It is obvious that in practice numerous changes may be introduced inconstruction and arrangement without constituting a substantialdeparture.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination in a draw-gear, of the metallic draft-plates securedto the perpendicular sides of the central stringers by horizontal boltsand provided with front and rear follower-castings upon their innerfaces, said castings having holes through which are passed perpendicularbolts which secure the castings to the central stringers.

2. The combination with the metallic draftplates secured to theperpendicular faces of the stringers by horizontal bolts passed throughthe said plates and stringers, of follower-castings having enlarged ends15 provided with bolt -holes through which are passed perpendicularbolts which secure the castings to the central stringers.

3. The combination with the metallic draftplates secured to theperpendicular faces of the stringers,- of follower-castings, and each ofsaid castings having a horizontal strengthening-rib and a bolt-holethrough which passes perpendicular bolt 34, uniting a casting to astringer.

4. The combination with the metallic draftplates, of frontfollower-castings riveted to the faces of the plates and each castingprovided with a bolt-hole at the end through which passes a bolt 37which unites the said casting to the end sill.

5. The combination with the metallic draftplates having lower horizontalflanges 8, of follower-castings riveted to the faces of the plates, andstay-plates secured to the lower flanges of the draft-plates by rivets;said stayplates extending from end to end of the metallic draft-platesand beneath the openings made in the sides of the said plates.

6. The combination with the metallic draftplates, offollower-castings,stay-plates, spring mechanism, and shims located underthe coupler-shank and also under the spring mechanism.

7. The combination with the metallic draftplates, of follower-castings;stay-plates; spring mechanism; and shims; said followercastings beingprovided with seats, as 16, for the shims.

8. The combination with the metallic draftplates, of a spring mechanism,and shims; the said draft-plates being provided with openings which arenormally closed by side plates which retain the shims' in position.

9. The combination with the metallic draftplates secured to the sides ofthe stringers, of follower-castings; a coupler and spring mechanism;stay-plates; a carry-iron; and a plurality of shims, which shims arelocated beneath the spring mechanism.

10. The combination in a draw-gear, of two central stringers; an endsill; and two draftplates provided with front and rear followercastings;the said draft-plates being secured to the stringers by bolts which passthrough the stringers, end sill, and castings; the said bolts which passthrough the end sill also passing through the ends of the frontfollower-castings.

11. A metallic draft-plate havinga bolster attachment 5 located at rightangles to the face of the plate, an end-sill attachment 6 located in ahorizontal plane and at right angles to the face of the plate, astringer attachment 7, midway the ends of the plate, and stay-plateflanges 8; the said draft-plate having an opening midway of its lengthand a stay-plate 10 secured by rivets to the flanges 8, as set forth.

12. The combination in a draw-gear, of central stringers; draft-platesprovided with follower-castings riveted to their faces; a springmechanism; and means for raising or lowering the spring mechanismrelative to the stringers, said means consisting of shims which can beremoved from beneath the followers and placed above the same.

13. The combination with the draft-plates, of the front and rearfollower-castings having seats 16 the stay-plates; shims resting uponthe stay-plates; followers supported upon the shims; a coupler andspring mechanism; and removable plates 22 at the sides.

In testimony whereof I aflix my signature in presence of two witnesses.

CHARLES WRIGHT.
